Active clinical trials for "Sleep Apnea Syndromes"

Obstructive sleep apnea (OSA) is a disorder where a person has recurrent choking episodes during sleep. Surgery can treat OSA and drug induced sleep endoscopy (DISE) is a procedure that surgeons use to evaluate the throat while a person is sedated, mimicking sleep, to help determine if surgery might be effective. Lung volume can influence OSA severity but the relationship between lung function and throat collapse seen on DISE has not been well studied. This study aims to see if lung volume influences what is happening in the throat during DISE. Participants will be recruited from the sleep surgery clinic where they are being evaluated for surgery to treat their OSA. Participants will have a DISE that is performed as part of their routine surgical workup for treatment of OSA. Additionally, during the DISE, they will participate in one of two study groups. One group will have a negative pressure "turtle shell" ventilator placed over the participants chest during DISE to manipulate lung volumes to see if it can improve throat collapse. A second group will have electrodes placed over the neck to stimulate the phrenic nerve to contract the diaphragm to improve lung volumes to see if it can improve throat collapse. Both groups will also have a lung function test performed.The findings of this study will be important in improving pre-surgical evaluation of patients to better predict if surgery can help as well as potentially develop new surgical therapies for the treatment of OSA.

According to a stratification procedure, the objective of a personalised care plan (VitalCare) is to identify points for improvement since the early stage of the patient's pathway of CPAP/APAP treatment and to adjust patient follow-up .

Sleep apnea including obstructive sleep apnea (OSA) and central sleep apnea (CSA), are common in patients with cardiovascular disease. The prevalence of OSA is 2%-4% in general population and 16%-47% in surgical-heart failure patients. The previous studies found that the sleep apnea types shifted from OSA to CSA after continuous positive airway pressure (CPAP) treatment or from CSA to OSA after heart surgery (cardiac valve replacement/ repair or heart transplantation) without the mechanism illuminated clearly. The recent studies found that the loop gain (LG) could predict the effect of upper airway surgery and CPAP treatment on the reversion of OSA. However, in patients with valvular heart disease, whether LG and related parameters can predict the therapeutic efficacy of CPAP or cardiac valve replacement is not expounded clearly. The investigators' previous study found that there were different outcomes of sleep apnea after cardiac valve replacement: elimination or consistent. But the corresponding non-anatomic mechanisms was not clear. The investigators' preliminary experiment showed that the LG and related parameters were not improved while OSA improved by CPAP treatment; however, the recovery of OSA after cardiac valve replacement was closed related to the improvement of LG and related parameters. The investigators speculated that, 1. LG and related parameters could predict OSA outcome of CPAP treatment or cardiac valve replacement. 2. non-anatomic mechanisms including LG and associated parameters, contributed to CPAP treatment and cardiac valve replacement were different. In this study, the investigators aimed to explore the relationship between LG and, outcomes of OSA and the regarding non-anatomic mechanisms in patient with heart valve disease.

Maxillomandibular advancement (MMA) surgery, one of the most successful surgical procedures for the treatment of obstructive sleep apnea (OSA), is predominantly used to manage patients with moderate to severe OSA. However, limiting factors include incomplete response in some cases, unfavorable facial changes as a result of large advancements, and risk of malocclusion or malunion. This study will be done to determine predictors of success with MMA surgery in patients with moderate to severe OSA. Studies have already shown the value of a remote controlled mandibular positioner (RCMP) device to identify the correct level of therapeutic protrusion needed with oral appliance therapy. Moreover, some patients experience a dose dependent improvement in sleep parameters based on the degree of protrusion during the titration study. Use of RCMP as a means to identify potential candidates for MMA, may help customize treatment options for patients with OSA by providing predictive value.

This study is a single site pilot and feasibility study. We propose that 3D printing could be used to create customised masks for patients requiring Positive Airway Pressure (PAP) therapy. We hypothesise that the use of this technology may result in; improved compliance with therapy, increased comfort, reduced side effects, increased quality of life and reduced healthcare costs.

In the treatment of obstructive sleep apnea, by using sequential 4-channel electrical stimulation treatment, unlike conventional positive pressure devices, it can be done more effectively by improving the strength of the biceps and soft palate, which are the causes of sleep apnea. thought.

A feasibility randomized controlled trial will be conducted with a 6-month follow up to: Examine the impact of early intensive telemedicine motivational enhancement (TIME) vs standard of care on PAP adherence (n=40/group) and continuity of care at 3 and 6 months post-discharge in patients admitted with ADHF with a new inpatient diagnosis of OSA(REI>5). Assess the effect of early telemedicine integrated with motivational enhancement (TIME) vs standard of care on patient reported outcomes including Functional Outcomes of Sleep questionnaire (FOSQ-10), Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Investigate the impact of early TIME vs standard of care on 6-month hospital readmissions.

Sleep-disordered breathing (SDB or sleep apnea) is very common among elderly Veterans and leads to increased morbidity and mortality in this population. The proposal aims to identity whether oxygen, finasteride and acetazolamide can be effective in reducing unstable breathing and eliminating sleep apnea in the elderly via different mechanisms. This proposal will enhance the investigators' understanding of the pathways that contribute to the development of sleep apnea in the elderly. The investigators expect that the results obtained from this study will positively impact the health of Veterans by identifying new treatment modalities for sleep apnea. A cumulative effect of the investigators' research will fulfill the long-term goal of improving the quality of life of elderly Veterans suffering from sleep apnea and its potential life-threatening complications.

Obstructive sleep apnea (OSA) is a sleep disorder which is caused because of collapse of airway or inappropriate tongue position. As OSA becomes severe, the physical and psychological aspect might be influenced due to insomnia. In addition, many evidences revealed that OSA is related to cardiovascular disorder. Apnea-hypopnea index (AHI) and epworth sleepiness scale (ESS) are common parameters to evaluate the severity of OSA. Recently, body and tongue fat have certain relation with OSA, and the higher the fat, the more possible to get OSA. To find the treatments for OSA, myotherapy has been proved to improve AHI and ESS. The treat mechanism is speculated that increasing muscle tone around oral and oropharyngeal and decreasing tongue fat. High intensity interval training (HIIT) might be effective to OSA, for it could lower down the total body fat. Furthermore, HIIT is a time-efficient program which can increase exercise adherence. Last, less articles discussed about the effect of supervised verse unsupervised treatment and the effect of mix-model treatment. The purpose of the study is investigating the comparison between supervised HIIT plus myotherapy and unsupervised home exercise plus myotherapy. Method: 40 patients who meets the inclusion criteria will be recruited in this article during 2022/01 to 2022/12. Then, they will be randomly assigned into HIIT plus myotherapy group and home exercise plus myotherapy group. The treatment process will last for 8 weeks. All the outcomes such as AHI,ESS and body fat will be completed before and after 8 weeks treatment. The Wilcox signed test was adopted to analyze the treatment before and after the treatment sessions (time effect). The Mann-Whitney U was applied for the difference before and after treatment between two groups (group effect), and the baseline of two groups was also analyzed by this method. The significant level was set as p value< 0.05. Hypothesis: It is speculated that HIIT plus myotherapy might revealed better outcomes on AHI, ESS, and body fat.

Obstructive sleep apnea (OSA) is a common clinical condition associate with a negative impact not limited to the patients but also to the partner that sleep in the same bed. Is it reasonable to speculate that the partner suffer sleep deprivation, increased level of irritability, insomnia, fatigue, among others due to the loud snoring caused by the OSA patient. Although previous data reported impaired sleep quality in partners of patients with OSA, it is not clear in literature whether OSA promotes cardiovascular impact and if the treatment of OSA promotes some cardiovascular benefits in (the) partner beyond the improvements in the subjective and objective sleep. Thus, the main objectives of this randomized controlled study are: to evaluate the impact of three months of randomization (treatment with nasal CPAP or nasal strips) on the endothelial function, blood pressure (ambulatory blood pressure monitoring), sleep duration (wrist actigraphy for 1 week) and sleep quality (Pittsburgh Questionnaire) and the frequency of OSA in the bed partners of patients with moderate to severe OSA.
